Quality Control

Our production of this copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, acid value, glass transition temperature (Tg), and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at a controlled room temperature (15-25°C). Ensure the storage area is well-ventilated and away from sources of heat and ignition. Opened containers should be resealed immediately under a dry atmosphere to prevent moisture absorption, which can affect processing and final product properties.
